IVlACHiNE FOR 'BENDING SHANK S OF SAD-IRON HANDLES.

SPECIFICATION forming part of Letters Patent No. 294,509, dated March 4,1884:

' Application filed August 20, 1883. (No model.)

To all whom it may concern:

Be it known that I, JOHN SABOLD, J r., a citizen of the United States,residing at Little Oley, in the county of Berks and State ofPennsylvania, have invented certain new and useful ImprovementsinMachines for Bending Shanks of Handles for Sad-Irons, of which thefollowing is a specification.

My invention relates to a machine for bond ing the wrought-iron shanksfor handles for sad-irons to the conventional shape.

The construction of the parts comprising the machine and their operationwill first be de scribed, and then the parts and combinationsconstituting the invention will be designated in the claims. v

In the annexed drawings, which illustrate the invention, Figure 1 is afront elevation of the machine. Fig. 3 is a view of the handle andshanks before they are bent in position on the mandrel. Fig. 4. is aview of tlie handle with the shanks bent into its sides. Fig. 5 is asectional elevation of the machine.

In the manufacture of sad-irons that part of the handle which is graspedby the hand is usually made of cast metal. The smoothingblock is alsocast metal; but the handle-shanks which connect these parts are made ofwroughtiron. The handle is, cast with the wroughtiron shanks placed inthe niold in such position that when the mold is poured each end of thecast handle will take onto one end of one of the shanks. During thisoperation the wrought-iron shanks consist, simply,of a piece of straightrod, as shown in Fig. 3.

The machine which comprises the present invention is designed to receivethe above-described 'handle,with its straight wrought-iron parts, andbend the latter to the conventional shape, as shown in Fig. 4.

The letter A designates the upright frame or standard of the machine,made of fmetal. Preferably the entire standard is one casting.

B designates two vertical guides formed in the standard,in which thehead 0 slides. Two shank-formers, D, are suspended by the upper endsfrom the head. A pin, b, secures each former to the head; but the upperend of the former is rounded and has bearing in a correspondingly-shapedsocket on the under side of Fig. 2 is a View of the mandrel.

the head, whereby when the formers are pressed down by the head nostrain comes on the pin 1), and at the same time the pins 1) will serveas a pivot toadapt the lower ends of the formers to move laterallytoward each other. The lower part of each former is provided on one sidewith a V-shaped groove adapted to bear on the vertical guide B, and onthe opposite side of each former has a roller, 0. From the rollerdownward each former has two incline faces, (I e, which together producea V-shaped end.

I A forn1ing-mandrel, E, has a top surface, f, sunk to receive the grasppart of the handle of a sad-iron which is placed across it, and at eachend of the sunken surface is a raised shoulder, f, -on which the shanksof the ha-n-- dle rest, as shown in Fig. 3, and has sides wh1ch,near thetop,proj ect and curve outward,

as at g, and then below are hollowed or curved former, and then, as thedownward movement of the formers continues, the latter are, by theblock-guides, crowded overlaterally toward the hollowed part 71. of themandrel. The blockguides are adjustable in a horizontal direction to orfrom each other, and are held to any position by means of the set-screws7a. This adjustment enables the block-guides to be set to suit differentsizes of shanks.

The parts just described comprise those which are directly employed inbending the shanks, and the operation is as follows: The grasp part ofthe handle is placed on the top surface of the mandrel E, and theshank-formers D are moved down. The first effect is the V-shaped ends ofthe formers press the straight shanks downward. Then the inclined facesd take effect and press the shanks down still farther. Then, when theinclined faces '62 come against the rollers t of the block-guides,'thelower ends of the formers are thereby crowded over laterally toward themandrel. This brings the rollers c of the formers hard against theshanks, and the latter are then pressed into the hollowed parts h of thesides of the mandrel. Thus, by one downward movement of the pivoted andsuspended shank-formers, both of the shanks are bent tothe desired shapeat once. The handles may now be removed from the mandrel by hand or byany suitable means. For this purpose I provide a pusher, n, whichreciproeates across the top of the mandrel. This pusher is attached to ahead, 01, which has the lower part of its rear side beveled or inclineddownward, as shown at p in Fig. A rod, q, is attached to the head a, andpasses freely through ahole, q, in the body of the mandrel, and when thepusher reciprocates this rod slides in the hole. A head, 9', 011 the rodis underlaid with a soft washer, and this serves to stop the pusher whenit is moved back. Two pins, .s', project from the head, one of whichbears 011 each side of the body of the mandrel. The pusher is movedforward to remove the sad-iron handle by a vertieally-movable rod, T,which has on its lower end a head with an upwardly-inelined face, 1).This rod is attached by its upper end to the bolt 3, which connects thelever with the large head 0. \Vhen thishead moves up, the inclinedface 1) on the lower end of-the rod T bears against the inclined rearside, p, of the pusher-head, and thereby the pusher is moved forward,causing the handle to slide from the mandrel. A spring, 11, attached tothe standard bears against the pusher-head and moves it back. The headChas vertical movement imparted to it by the lever G,which is pivoted tothe standard at G. The head has a horizontal slot, 1, in which a block,2, slides, and the end of the lever is pivoted by a bolt, 3, to thisblock. The other end of the lever has a weight, G'", to counterbalanceand elevate the head. Standards 11 have boxbearings I for a rotaryshaft, 4, on which a.

cam, J, is keyed. This cam serves to raise the weighted end of thelever, as indicated by broken lines, and thereby moves thehead andshank-formers down. A gear-wheel, K, is

Having described myinvention, I claim and desire to secure by LettersPatent of the United States- 1. In a machine for bending the shanks ofsad iron handles, the combination, substantially asset forth, of astationary mandrel having a sunken surface, f, to receive the grasp partof the handle, a raised shoulder, f, at each end of said surface, andsides which curve first outward near said shoulders, and are thenhollowed inward, and means to bend both shanks about the mandrel atonce.

2. In a machine for bending the shanks of sadiron handles, thecombination, substantially as set forth, of a mandrel, vertical guides,a large head, 0, to move in the guides, two shank-formers, D, pivoted bytheir upper ends to the head, and each having aV-shaped lower end, andlaterally-adjustable block-guides F at each side of the mandrel,

3. In a machine forbendingthe shanks ofsad' iron handles, thecombination, substantially as set forth, of a mandrel, vertical guides,a large head, 0, to move in the guides, means to bend both shanks aboutthe mandrel, a pusher, 11, adapted to reciprocate across the top ofmandrel, and attached to ahead, u, having a downward-inclined side, 9),and a vertically-movable rod, T, having its upper end connected to thesaid large head, and provided on its lower end with an upwardly-inclinedface, 1).

4. In a machine for bending the shanks of sadiron handles, thecombination, substantially as set forth, of a mandrel of requisite form,a head moving in vertical guides, and having a horizontal slot, 1,provided with a slide-block, 2, two shank-formers, D, to bend bothshanks about the mandrel, a pivoted lever, G, having one end pivoted-tothe said. slide-block and the other end weighted, and a rotary shaftprovided with a cam to move the weighted end of the lever.

In testimony whereof I affix my signature in presence of two witnesses.
